It would be nice to have the ability to change the VON volume on individual channels via command, so that mission authors can make that option available ingame.

If there are several clients connected, it gets increasingly difficult (impossible) to hear radio communication in a specific channel (group, vehicle), if everyone talks in the side or global channel for example. The option to adjust the volumes on those channels would be a great help.

Command could have the structure:
adjustRadioVolume ["channel", volume];
"channel" - String, the channel to be used: Side, Global, Group, etc.
volume - Number of the volume, from 1 to 0; 1 meaning full volume, 0 meaning no volume, muted

Return Value: Array -> [VON channel, new volume]
